Polyurethane Foam-In-Place Packaging is a combination of an isocyanate and Polyol (resin), pre-formulated so they need to only be mixed and dispensed. Foam-in-place packaging is a highly useful technique for on-demand protection of packaged objects. In its most basic form, foam-in-place packaging comprises injecting foamable compositions from a dispenser into a container that holds an object to be cushioned. Typically, the object is wrapped in plastic to keep it from direct contact with the expanding foam. As the foam rises, it expands into the remaining space between the object and its container thus forming a custom cushion for the object.
